What is the best way to do melee weapon collision?

Yeah but hit events NECESSARILY include the depenetration of the two colliding bodies.

An animation which drives a capsule or box collider through an enemy cannot produce OnHit events, by definition.
It might be possible to, instead of using attachment, sweep the collider shape to a new location each tick, but even if this accounted for rotation properly (and it doesn’t, sweeping never does) the shape would get stuck on the enemy and break collision detection thereafter, which is not intended behavior.

As far as I’ve found out so far, its a really expensive operation - to obtain the overlapping area, which I suggested.
After a quick google search I’ve found the following (check the links in the comments throughout the threads)

algorithm - Finding shared volume of two overlapping cuboids - Stack Overflow
geometry - Computing a volume (area) of intersections - Mathematics Stack Exchange
Reddit - Dive into anything

Regarding your depenetration sentence, what exactly does that mean? The volume will ‘return’ back to its position before the hit? Will it freeze there? Or will it simply not produce overlap events?
